Installation

Installation of these plugins to the remote server helps in sharing data or information across datasets. There are two parts to this process:

Log in to the REDCap server and navigate to the REDCap install directory containing the file redcap_connect.php and database.php files.
Following are example commands executed in our dev environment.
$ cd /home/var-www/html/redcap/ $ ls database.php redcap_connect.php database.php redcap_connect.php
Create a new 'plugins' directory if not present.
$ mkdir -p plugins
Copy the REDCap_PHP file to the plugin's directory.
$ cp $RC_OS_PLUGIN/openspecimen_plugin.php plugins
To ensure that the plugins are correctly installed, you can invoke the following API using the HTTP client program of choice or run the commands as shown below.

Below is an example done using Postman
1. Replace <host> with hostname where REDCap server is deployed
2. Replace <Project API token> with actual API token issued for accessing REDCap project using APIs
3. In response, you should see the REDCap audit log events nicely formatted using JSON.
The following commands should succeed with printing JSON string on the console.
1. RC_HOST - URL of the REDCap server. E.g. https://redcap.openspecimen.org
2. RC_DOCROOT - Document root of the REDCap server. E.g. /, /r
3. OS_PLUGIN - Relative path of the OpenSpecimen REDCap plugin w.r.t document root. E.g. /plugins/openspecimen_plugin.php
